Emperor Romanos III Argyros decides to retaliate upon the incursions of the Muslims on the eastern frontier. He leads a Byzantine expeditionary force (20,000 men) to secure Antioch. The Mirdasid emir Shibl al-Dawla NasrofAleppo sues for peace, but Romanos refuses to negotiate and leads his army against Aleppo, against the advice of his generals. The Byzantine army encamps near Azaz, where they are encircled by the Mirdasids' Bedouin troops, who cut off the Byzantines from food and water.
10 August – Romanos orders a retreat to Antioch. As the army is exhausted from the heat and the lack of supplies, the retreat soon turns into a flight in panic.

In April/May 1031, Emir Nasr of Aleppo agreed to vassal and tributary status with Byzantium.^[1]
